Really Confused

Here is the prompt. I am really confused on how to set this up and what methods to use.

So back to that ScrabblePlayer. I found that it's not enough to know if they just have a tile of a specific character. We need to know how many they actually have. Can you please add a method called getTileCount that uses the for each loop you just learned to loop through the characters and increment a counter if it matches? Return the count, please, thanks!

ScrabblePlayer.java 
public class ScrabblePlayer {
  private String mHand;

  public ScrabblePlayer() {
    mHand = "";
  }

  public String getHand() {
   return mHand;
  }

  public void addTile(char tile) {
    // Adds the tile to the hand of the player
    mHand += tile;
  }

  public boolean hasTile(char tile) {
   return mHand.indexOf(tile) > -1;
  }

  public String getTileCount() {
    for() {
      //What to put here?
    }
  }
}

Hey Marcus,

You simply need to create a new method, which accepts a char elemnt and checks how many times it occurs in the palyers' hand:

  public int getTileCount(char tile) {

//Initialize the count variable which will store the number of occurences

    int count = 0;

// go through each and every char of the string mHand. To do that you need to use the .toCharArray() method.

    for (char pointer : mHand.toCharArray()) {

// if a tile from the string is equal to the parameter increment the count

      if (pointer == tile) {
        count++;
      }
    }
    return count;
  }
